My invention relates to a secondary manifold for supplying and distributing Vsupplemental gases-.preferably mixtures of eX-` haustf gas of the engine and air, with or without `additional fuel-to the intake manilfold leading from the carburetor and'throt'- tle of an internal combustion engine to the engine cylinders.

principal object of the invention is the` provision of such a secondary manifold, whlch is made 1n parts or sections that are adjustable rin relation to one another, and which is of substantially universal applica# tion to intake manifolds of various engines' and constructions, so that' servicestations installing my equipment for supplying sup'- plemental charge material as 'an accessory'v on old engines need not keep on hand large stocks of secondary manifolds specially'con structed to fit each` of the large number of engines and manifolds of various makesland` sizes, but can meet practically "anyrequire-- ment'with a limited number ofsimp'le` stock parts. u Inthe accompanying drawings illustrating embodiments of thel invention, Fig. l1'@ is aplan view, partly in section,'of an in" take manifold for a sixcylinder engine and havingattached theretoasecondary manifold embodying my invention.l Fig. 2 is a side view, partly in section, ofthe secondary'.

manifold shown in Fig. 1'; Fig. 3 is a vievir similar to Fig. 2 of the, secondary manifold,` assembly with the central section omitted for'application to an intake manifold havf 4 is across ing two main branches, and Fig.

Reference character designates the tafkemanifoldof an internal combustion en?? gine havingthree main branches 12,14 and 16 (which in turn subdivide in the usual way" to enter the six intake valve ports" of asifii'f cylinder engine).

Bolts 52 passing through holes. 50 and screwed? into the tapped holes 38 in the nozzle'member flanges 36 serve tof connect the manifold sections to the nozzle members. In making up the connectionfsuitable gaskets are preferably used in orderto secure a gastight connection. -Where the secondary :manifold is connee'ted'to a; four cylinder engine and but'two secondary manifold `fsection'sare used, as in Fig.j 3, the reduced-fendportion 54y of sec-Y'l tion 44 is 'received in the enlarged end por.-
